The combustion of natural gas emits greenhouse gases. Thus 1 kWh of natural gas produces approximately 0.186 kg of CO2 which is released into the atmosphere. Also, it is now possible to neutralize these emissions via several green offers from gas suppliers.

Like electricity, green gas is growing steadily. Reducing the impact of gas on the environment can be achieved through carbon offset gas (whose CO2 emissions are captured by suppliers’ partners) or biomethane (derived from the mechanization of organic waste).

A principle of carbon offset gas

To compensate for the emissions caused by the use of natural gas by a household, a supplier proceeds to the purchase of carbon credits. The funds thus collected allow authorized associations to carry out actions to preserve the environment.

Under the Kyoto Protocol’s principle of geographical neutrality, these credits are certified and standardized to be easily verifiable and tradable all over the world – under the control of the World Bank.

Emissions compensation can take two forms:

  • Financial support for organizations working to reduce air pollution or promote green technologies.
  • Support for the development and protection of forest areas to help capture greenhouse gases released into the atmosphere (trees absorb CO2 through the phenomenon of photosynthesis).

Thanks to these credits, the supplier eni, for example, helped finance the construction of a methanizer – a facility that captures and exploits greenhouse gas emissions – in an outdoor dump in Thailand. (Recycling 635,000 tons of CO2 emissions), or fume extraction systems for charcoal stoves in Ghana (65,000 tons of CO2 per year).

Similarly, EDF is working to reduce emissions from the Chinese electricity grid, mainly fueled by fossil fuels, by supporting the development of generators powered by water vapor produced by burning agricultural waste.

The purchase of carbon credits impacts the price of the kWh of gas consumed. However, green supply is not necessarily less competitive than regulated gas supply – for which emissions are not offset.
